3.0.0pre2: non-recursive remote listing breakage

Looks like pre1's fix broke something else.

I noticed this when listing module/directory contents on servers known
to be running versions 2.5.7 & 2.6.3. Not having (full) access to them,
I replicated the errors using 2 machines on my home lan.


# the machines
lithium.elements.lan: the client. rsync 3.0.0pre2 for all tests.
fluorine.elements.lan: the server with slack mirror mockup. All rsync
versions from 2.6.9 back to 2.5.5 (to cover all the bases).


# the test
rsync rsync://fluorine.elements.lan/slackware/


# the results
(2.6.9 to 2.6.4)
motd & module contents displayed as expected.

(2.6.3, as seen on lithium)
<snip motd, if any>
rsync: on remote machine: -d: unknown option
rsync error: requested action not supported (code 4) at clientserver.c(473)
rsync: read error: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(755)
[receiver=3.0.0pre2]

(2.6.2 to 2.5.5, as seen on lithium)
<snip motd, if any>
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(596)
[receiver=3.0.0pre2]

(2.6.2 to 2.5.5, as seen in fluorine's logs)
Oct 12 18:05:03 fluorine rsyncd[2733]: rsync on slackware/ from
lithium.elements.lan (192.168.1.3)
Oct 12 18:05:03 fluorine rsyncd[2733]: on remote machine: -d: unknown option
Oct 12 18:05:03 fluorine rsyncd[2733]: rsync error: requested action not
supported (code 4) at clientserver.c(424)


Apologies for not reporting this earlier. Real life got in the way.

That is a known limitation of the removal of a really old kluge in the
listing code.  To quote from the NEWS file:

- Requesting a remote file list without specifying -r (--recursive) now
  sends the -d (--dirs) option to the remote rsync rather than sending
  -r along with an extra exclude of /*/*.  If the remote rsync does not
  understand the -d option (i.e. it is 2.6.3 or older), you will need to
  either turn off -d (--no-d), or specify  -r --exclude='/*/*' manually.
